Hi, The gfs_mkfs manual page (RHEL 5.0) says: If not specified, gfs_mkfs will choose the RG size based on the size of the file system: average size file systems will have 256 MB RGs, and bigger file systems will have bigger RGs for better performance. My 3 TB filesystems still seem to have 256 MB RG's (I don't know how to see the RG size, but there are 11173 of them, so that seems to indicate a size of 256 MB). Is 3 TB considered to be "average size"? ;-) Anyway, it is recommended trying to rebuild the fs's with "-r 2048" for 3 TB filesystems, each with between 1 and 2 million files on it? Especially gfs_scand uses *huge* amounts of CPU time and doing df takes a *very* long time....
